Press mixture into a log and chill.
Divide cheese mixture to equal number of eggplant slices and put one portion in center of each slice.
Fold eggplant over filling to make a roll.

Variations: If you can use egg, mix egg into the filling mixture and blend to a smooth paste.
Chill mixture.
If you can use wheat and gluten, coat eggplant slices in a mixture of wheat flour and raw wheat germ instead of the brown rice flour or potato flour.
If you can use gluten but not wheat, you can substitute oat flour for the brown rice flour or potato flour.
For a milk-free version, you can substitute a meat filling such as those for Chinese Dumplings or Potlickers
